 Proposal #2:To approve the adoption by the Board of an amendment of Article IV of the Company's charter to increase the authorized shares from 28 million shares to 38 million shares, a 36% increase.   
    
  At February 28, 2017, the Company had 25.5 million shares of common stock outstanding or reserved for issuance under the Company's Stock Incentive Plan, approximately 91% of the total number of shares currently authorized for issuance, leaving approximately 2.5 million shares available for issuance.  This limits the Company's flexibility if shares are needed for raising funds, for acquisitions, or for other, general corporate purposes.  If the amendment is approved, the Company will have approximately 12.5 million shares available for issuance for these purposes.   
    
  The Board of Directors believes that an increase in the number of authorized shares is advisable so that the Company will have enough shares to implement an acquisition strategy, to raise capital, and for other corporate purposes.   
    
  More information about this amendment can be found below under the headingAmendment of Article IV of the Certificate of Incorporation (Proposal 2)on Page 9.

More information about this amendment can be found below under the headingAmendment of Article VI of the Certificate of Incorporation (Proposal 3) on Page 9.

Grant Thornton was the Company's firm of independent auditors for 2016. More information about Grant Thornton and their fees can be found below under the headingInformation About Audit Fees & Audit Services on Page 37.

Proposal 1.To be elected a director, a nominee must receive more votes for his or her election than against it. Because the election of a nominee does not require a minimum number of votes, abstentions and broker non-votes will have no effect on the voting for the election of directors.
Proposals 2 & 3.The approval of the two amendments of the Company's Certificate of Incorporation requires the affirmative vote of the holders of a majority of the outstanding shares of common stock of the Company. As a result, an abstention and broker non-vote will have the affect of a vote against the proposal.
Proposal 4.The ratification of the selection of Grant Thornton LLP as the Company's independent registered public accounting firm for 2017 requires the affirmative vote of the holders of a majority of the shares of common stock who are present in person or represented by proxy at the Annual Meeting and who are entitled to vote on that proposal.

AMENDMENT OF ARTICLE IV OF THE CERTIFICATE OF INCORPORATION
(Proposal 2)

Adoption of the Amendment. On November 4, 2016, the Board of Directors adopted, subject to the approval of the stockholders, an amendment of Section 4.1(b) of Article IV of the Company's Certificate of Incorporation (charter) to increase the number of shares of common stock that the Company is authorized to issue from 28 million shares to 38 million shares. In accordance with the Delaware General Corporation Law (DGCL), the Board has declared the amendment to be advisable.

The amended Section 4.1(b) reads as follows:

[4.1] "(b)     The number of shares of Common Stock that the Corporation has authority to issue is thirty-eight million (38,000,000) with a par value of one cent ($0.01) per share."

Reasons for the Amendment. At February 28, 2017, the Company had 25.5 million shares of common stock outstanding which includes the 492,046 shares reserved for issuance under the Company's Stock Incentive Plan. With approximately 91% of the total number of shares currently authorized for issuance outstanding or reserved, only 2.5 million shares remain available for issuance. This limits the Company's flexibility if shares are needed for raising funds, for acquisitions, or for other, general corporate purposes. If the amendment is approved, the Company will have approximately 12.5 million shares available for issuance for these purposes.

The Company has grown through acquisitions and seeks to have a portion of the acquisition purchase price payable in shares of common stock so that the seller has an incentive to support and contribute to the success of the Company after the acquisition, whether or not the seller remains part of the Company.

Effect of the Issuance of Newly-Authorized Shares. The issuance by the Company of additional shares of common stock would have the effect of diluting the percentage ownership of current stockholders of the Company. In addition, in the absence of a proportionate increase in the Company’s earnings and book value, an increase in the number of outstanding shares of common stock would dilute the earnings per share and book value per share of outstanding shares of common stock.

The Board of Directors recommends that stockholders votefor the approval of the
Amendment of Section 4.1(
b) of Article IV of the Certificate of Incorporation

AMENDMENT OF ARTICLE VI OF THE CERTIFICATE OF INCORPORATION
(Proposal 3)

Adoption of the Amendment.Under theDelaware General Corporation Law (DGCL), only a board with classified directors can provide that directors may only be removed for cause, and Section 6.4 (Removal of Directors) of Article VI of the Company's charter contains that provision. Until the 2017 Annual Meeting, the Company had classified directors.At the 2014 Annual Meeting, stockholders approved an amendment to the charterto phase out the classified board over three years beginning with the 2015 Annual Meeting. As a result, at the 2017 Annual Meeting, the Board's directors will no longer be classified.

Therefore, in order to bring the charter into compliance with Delaware law, on November 4, 2016, the Board voted to amend Section 6.4 to eliminate the requirement for cause in the removal of directors. The amended section reads as follows:

- 9 -

"6.4    Removal of Directors. Subject to the rights of the holders of any outstanding series of Preferred Stock, any director or the entire Board of Directors may be removed from office at any time by the affirmative vote of the holders of a majority of the combined voting power of the then outstanding shares of capital stock of all classes and series of the Corporation entitled to vote generally in the election of directors, voting together as a single class."

If the amendment is not approved, Section 6.4 will remain out of compliance with Delaware law, but directors may nevertheless be removed with or without cause.

Pursuant to the DGCL, the Board of Directors has declared the amendment of Section 6.4 of Article VI to be advisable.

Required Approval and Effective Date of the Charter Amendments in Proposals 2 and 3. The approval of an amendment to the charter requires the affirmative vote of the holders of at least a majority of the Company's outstanding shares of common stock. At February 28, 2017 the record date for the 2017 Annual Meeting, there were 25,051,045 shares of common stock outstanding. An amendment approved by stockholders will become effective when it is filed with the Secretary of State of the State of Delaware, which the Company intends to do promptly after the 2017 Annual Meeting. However, in accordance with the DGCL, notwithstanding the authorization of the proposed amendments by the stockholders, the Board is permitted to abandon either or both amendments without further action by the stockholders, but it has no intention of doing so.

The Board of Directors recommends that stockholders votefor the approval of the
Amendment of Section 6.4 of Article VI of the Certificate of Incorporation

RATIFICATION OF THE SELECTION OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM(Proposal 4)

Pursuant to its charter, the Audit Committee is responsible for the appointment of the Company's independent registered public accounting firm. The Audit Committee has selected Grant Thornton LLP to perform the audit of the Company's 2017 financial statements. Grant Thornton was also the Company's 2016 independent registered public accounting firm.

The Audit Committee may select a different independent registered public accounting firm at any time during the year if it determines that to do so would be in the best interests of the Company and its stockholders. The Board is asking stockholders to ratify the selection of Grant Thornton as a matter of good corporate practice, although ratification is not required by law or by the Company's Bylaws, and the vote is not binding on the Audit Committee. There is information about Grant Thornton's fees below under the headingInformation About Audit Fees & Audit Services.

The ratification of the selection of Grant Thornton requires the affirmative vote of the holders of a majority of shares of common stock present in person or represented by proxy at the meeting and who are entitled to vote on this proposal.

APPROVAL OF THE COMPANY’S NAMED EXECUTIVE OFFICER COMPENSATION FOR 2016 (an advisory vote)(Proposal 5)

Current SEC regulations require the Company to solicit an advisory stockholder vote on the compensation of the executive officers of the Company who are listed below in the section entitledThe Executive Officers under headingExecutive Compensation. The advisory vote, as described below, is commonly referred to as say-on-pay. The vote is not binding on the Company.

At the 2016 Annual Meeting, the holders of common stock present in person or represented by proxy at the meeting and who were entitled to vote on the Company's 2015 executive compensation voted as follows:

Number of Shares
Entitled to Vote
Voted ForVoted AgainstAbstained
14,586,62313,640,928 (93.5%)509,528 (3.3%)436,167 (3.2%)

In determining how to vote on the Company's 2016 executive compensation, stockholders should take into account all of the disclosures in this Proxy Statement that relate to the compensation of executives. That information includes a discussion and tables that are found below under the headingExecutive Compensation, as well as an explanation of why and how the types and levels of executive compensation were determined.

In the event that stockholders do not approve executive compensation, the Compensation Committee of the Board will review its decisions on compensation structure and levels, as well as the comparability of the executives' compensation to that of a peer group of companies, before deciding whether to make any changes in the compensation of one or more of the executives. The affirmative vote of the holders of a majority of the shares of common stock who are present in person or represented by proxy at the Annual Meeting and who are entitled to vote on this proposal is required to approve executive compensation.

The Board of Directors recommends that stockholders votefor the approval of

named executive officer compensation pursuant to the following resolution:

Resolved, that the compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion set forth below under the headingExecutive Compensation, is hereby approved on a non-binding, advisory basis.

THE FREQUENCY OF THE VOTE ON EXECUTIVE COMPENSATION (an advisory vote)
(Proposal 6)

In addition to the approval of executive compensation, current SEC regulations also require the Company to solicit a stockholder vote on the frequency with which the Company should conduct a vote on executive compensation. The vote is commonly referred to as say-on-frequency. At a minimum, the vote on executive compensation must be held at least every three years, and the vote to select the frequency of voting on executive compensation must be held every six years. Stockholders may vote to hold the vote on executive compensation each year, every two years, or every three years, or they may abstain from voting. It should be noted that stockholders are not voting to approve or disapprove the Company's frequency recommendation, but will vote on which of the three frequency choices they prefer. The vote is advisory in nature and therefore does not bind the Company. At the 2011 Annual Meeting, stockholders voted as follows for the frequency of executive compensation votes:

- 11 -

Every One YearEvery Two YearsEvery Three YearsAbstained
11,232,700 (92.2%)20,223 (0.2%)869,492 (7.1%)57,379 (0.5%)

In accordance with the 2011 vote, and as the Board recommended at the time, the Company has held say-on-pay votes annually. The next advisory vote on say-on-pay after the 2017 Annual Meeting will depend on the outcome of the say-on-frequency vote at the 2017 Annual Meeting. The Company believes that a vote every year will enable the Compensation Committee to take into account stockholders' approval or disapproval of executive compensation prior to renegotiating any new compensation arrangements.

In the event that stockholders elect to hold the vote on executive compensation every two or three years, the Board will honor that determination. The affirmative vote of the holders of a majority of the shares of common stock represented and entitled to vote at the Annual Meeting is required to select the frequency of stockholder votes on executive compensation.

the board recommends that stockholders vote "for every one (1) year" as the
frequency for holding a stockholder vote on executive compensation

Declassificationour board and meetings of Directors. As described above under the headingElection of Directors (Proposal 1), the process of phasing out the classificationeach committee on which such director served. Messrs. Cutillo and Messer did not join our board of directors is complete so that atuntil April of 2017.

We expect our directors to attend the 2017 Annual Meeting, all director terms of office are for one year.

Election of Directors by Majority Vote. In order to be elected a director, a nominee must receive more votes for his or her election than against it, which is commonly referred to as a majority vote. Because a director is elected for a specified term and until his or her successor is elected and qualified, an incumbent director who is nominated for re-election, but fails to receive a majority vote, would remain a director because no successor had been elected. To cure this problem, each incumbent director, as a condition to being nominated for re-election, must, in advance of the Annual Meeting, submit a resignation that becomes effective if he or she does not receive the required vote, and if the Board accepts the resignation. Before the Board makes a determination on accepting or rejecting the resignation, the Corporate Governance & Nominating Committee considers the matter and makes a recommendation to the Board. Each of the nominees has furnished the Board with the required contingent resignation.

Directors' Attendance at Meetings in 2016. During 2016, the Board held 20 meetings; the Audit Committee held seven meetings; the Compensation Committee held five meetings; and the Corporate Governance & Nominating Committee held five meetings. The meetings were held in person or by conference telephone call. During 2016, each incumbent director attended, in the aggregate, at least 97.3% of theannual meetings of the Board and of the committees on which he or she served.

Board Committees
To provide for effective direction and management of our business, our board has established three standing committees: an audit committee, a compensation committee and a corporate governance and nominating committee. Each of the audit, compensation and corporate governance and nominating committees are composed entirely of independent directors. Each committee operates under a written charter adopted by our board. All of the committee charters are available on our website at www.strlco.com under Investor Relations–Corporate Governance and are available in print upon request.

Consideration of Director Nominees
In evaluating nominees for membership on our board of directors, the corporate governance and qualifications of the nominees is set forth above in the section entitledBackground & Skills of the Nominees & Continuing Director under the headingElection of Directors (Proposal 1).

The Corporate Governance & Nominating Committeenominating committee has not specified any minimum qualifications for serving on the Board,board, but seeks to achieve a Boardboard that is composed of individuals who have experience that is relevant to the needs of the Company,company, who have a high level of professional and personal ethics,integrity, who have the ability and willingness to work cooperatively with other members of our board and with senior management, and who contribute to the cognitive diversity of the Board,board taking into account many factors, including business experience, public sector experience, professional training, public and private offices held, geographical representation, race, gender and age, among other considerations. Experience in the construction industry and in one or more of engineering, transportation, finance and accounting, corporate governance, senior management, and public sector matters are considered particularly valuable. An independent director candidate is expected to be committed to enhancing stockholder value, and to have sufficient time to carry out the duties of a director,

both on the full Boardboard and on one or more of its standing committees.

In selecting nominees, the corporate governance and nominating committee will seek to have a board of directors that represents a diverse range of perspectives and experience relevant to the company. The Corporate Governance & Nominating Committeecorporate governance and nominating committee will also evaluate each individual in the context of our board as a whole, with the objective of recommending nominees who can best perpetuate the success of the business, be an effective director in conjunction with the full board, and represent stockholder interests through the exercise of sound judgment using his or her diversity of experience in these various areas. In determining whether to recommend a director for re-election, the corporate governance and nominating committee will also consider the director’s age, tenure, past attendance at meetings and participation in and contributions to the activities of our board.

The corporate governance and nominating committee will regularly assess whether the size of our board is appropriate, and whether any vacancies on our board are expected due to retirement or otherwise. In addition, the corporate governance and nominating committee periodically assesses the strengths, experience, qualifications, attributes and skills of the independent directors to determine if there is a gap in the skills or experienceare gaps that the Boardboard should seek to fill. GivenIn the Company's size,event that vacancies are anticipated, or otherwise arise, the Committee realizes that it is difficult to achieve a Board with broad diversity. Whenever it is determined that replacement directors or additional directors are needed, the Corporate Governance & Nominating Committeecorporate governance and nominating committee will perform a similar assessment.

In identifyingconsider various potential candidates, who may come to the corporate governance and nominating committee’s attention through professional search firms, stockholders or other persons. Alternatively, the corporate governance and nominating committee may recommend a reduction in the size of the board.

Proposal No. 1: Election of Directors
In accordance with our bylaws, effective as of the annual meeting, our board of directors has fixed the current number of directors at seven. Upon recommendation of our corporate governance and nominating committee, our board of directors has nominated Joseph A. Cutillo, Marian M. Davenport, Maarten D. Hemsley, Raymond F. Messer, Charles R. Patton, Richard O. Schaum and Milton L. Scott to serve as our directors, each until the next annual meeting and election of their successor. All of the nominees are current directors. Each nominee has consented to being named as a nominee in this proxy statement and to serve as a director if elected. The persons named as proxies intend to vote your shares of our common stock for the election of each of the director nominees, unless otherwise directed. If, contrary to our present expectations, any of the nominees is unable to serve, the proxy holders may vote for a substitute nominee. The board has no reason to believe that any of the nominees will be unable to serve.
Our board and the corporate governance and nominating committee are considering the expansion of our board and are in the process of identifying qualified candidates with highly additive skills and relevant experience to maximize the Board’s effectiveness. We believe that nominating a director to serve the company is a significant undertaking that requires a thoughtful and diligent process, both in the identification of a pool of potential candidates and in determining which specific candidate will best serve the company. Although this process was not completed in time to nominate a new director at the annual meeting, we hope to select a candidate soon, and will follow the election procedures set forth in our bylaws. In selecting a nominee to serve as a member of our board, the corporate governance and nominating committee will adhere to the principles outlined in our board governance guidelines and will be mindful of the Board’s desire to increase Board diversity. See “Consideration of Director Nominees” for more information.
Vote Required to Elect Director Nominees
Under our bylaws, in an uncontested election, our directors are elected by a majority of the votes cast. In contested elections where the number of nominees exceeds the number of directors to be elected, directors are elected by a plurality vote, with the director nominees who receive the most votes being elected.
As a condition to nomination for election or reelection to the Board, each incumbent director or director nominee submits to the board in advance of the annual meeting an executed irrevocable letter of resignation that is deemed tendered if the director fails to receive the votes required for election or reelection. Such resignation shall only be effective upon acceptance by the board of directors, which effective time may be deferred until a replacement director is identified and appointed to the board.
If an incumbent director fails to achieve a majority of the votes cast in an uncontested election, the corporate governance and nominating committee will make a recommendation to the board of directors on whether to accept or reject the resignation, or whether other action should be taken. The board of directors will act promptly on the corporate governance and nominating committee's recommendation, considering all factors that the Board of Directors believes to be relevant, and will publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. For more information on the voting requirements, see “Questions and Answers about the Proxy Materials, Annual Meeting and Voting.”

Compensation DiscussionGovernance and AnalysisBest Practices. This discussion and analysis of
Our executive compensation coversprogram is designed and managed by the independent compensation awardedcommittee of our board. The committee annually reviews the components and structure of our compensation program to earned by, or paidensure that the program supports our business objectives and is aligned with the interests of our stockholders. As part of this review, the committee seeks input from its independent compensation consultant as it deems necessary to the named executive officers. It covers the material elementsprovide an outside perspective and evaluation of their compensation, including the following:

our program. The objectives of the Company's compensation programs and what they are designed to reward;
The elements of the named executive officers' compensation, and why the Compensation Committee has chosen those elements;
How the amounts and compensation formulas were determined, and how they fit into the Company's overall compensation objectives; and
The results of the most recentcommittee also values our stockholders’ views on our program. Based on last year’s annual stockholder advisory vote on executive compensation.

The objectivescompensation (say-on-pay), more than 90% of our stockholders indicated their support for our program.


We believe the Company'sfollowing compensation programsgovernance practices and what they are designed to reward. The Compensation Committeepolicies promote the accountability of our executives and strengthen the Boardalignment of Directors, which is currently composed of three directors, all of whom are independent, oversees and approves the compensation of the named executive officers. The Committee's compensation objectives are as follows:

To provide a rate of pay for the work the executive does that is appropriate in comparison to similar companies in the industry, and that is considered fair by theour executive and the Committee;stockholder interests:
To give the executive a significant incentive to perform at a high level, to reward that level of performance if achieved, and thereby to contribute to the Company's financial success;
To give the executive an incentive to remain with the Company; and
In the case of newly-hired executives, to provide them with an incentive to leave a prior employer and join the Company, and in some cases, to relocate.
22

The elements of the named executive officers' compensation, and why the Compensation Committee has chosen those elements.

Except as noted otherwise, executives are compensated through annual salaries and an incentive compensation plan. Annual salaries are designed to compensate the executive for the performance of his or her day-to-day responsibilities. The incentive compensation arrangements are designed to give the executives the opportunity to earn additional compensation, a portion of which — currently 50% — is paid in shares of the Company's common stock, if certain goals are met, that are subject to restrictions on their transfer and to forfeiture under certain circumstances.

Performance-Based Incentive Compensation. Incentive compensation consists of both cash and Company shares. While cash is an obvious incentive, the stock portion of incentive compensation is designed to encourage executives to take a longer-term perspective in fulfilling their responsibilities, and to align their financial interests with those of the Company's stockholders.

Incentive compensation is performance-based because it is dependent on the achievement of Company financial goals and the executive's individual performance goals. Financial goals, which for some executives also include operating-unit financial goals, tie a portion of incentive compensation to the team effort required for Company-wide success, while the individual performance goals are designed to concentrate the executives' attention on their own contributions to the overall effort.

Change-in-Control Agreements. The Company does not currently have a change-in-control severance agreement with any employee. However, it is the Committee's policy to provide that restrictions on outstanding restricted stock lapse in the event of a change in control because the Committee believes that the adverse effect on non-transferable stock held by employees when a change in control occurs, particularly in a public company, can be significant. The Compensation Committee believes that change-in-control agreements may become appropriate for executives whose employment is likely to be adversely affected by a change in control. Change-in-control agreements can be in the best interests of the Company and its stockholders because they provide the executive with a clear incentive to remain neutral as to any change-in-control transaction, should one arise, and undistracted by concerns as to his or her future employment. Generally, the Committee believes that change in control severance should only be payable if the executive's employment is terminated without cause shortly before, or within a year or two after, the change in control.

Compensation Best Practices:

ØIncentives Based on Performance – awards under our annual incentive program are based on the achievement of company and individual performance goals.
Ø50% of Annual Awards Paid in Restricted Stock Units – our annual incentive program provides that 50% of the award is paid in cash and 50% of the award is paid in restricted stock units, that vest over a three-year period, thus aligning with our stockholders’ interests.
ØClawback Policy – cash and equity awards under our annual incentive program are subject to clawback.

ØAnti-Hedging Policy – we prohibit our executive officers and directors from entering into hedging arrangements with respect to our securities.
ØAnti-Pledging Policy – beginning in 2018, we prohibit our executive officers and directors from pledging our securities.
ØExecutives Subject to Stock Ownership Guidelines – although we have required our executive officers to maintain certain levels of ownership in our company, in January 2018 we strengthened our stock ownership guidelines requiring each executive officer to acquire and maintain ownership of shares equal to a certain multiple of his base salary (5x for CEO, 3x for other executive officers). See “Stock Ownership Guidelines” below for more information.
ØEngagement of Independent Compensation Consultant – as necessary, the compensation committee retains an independent compensation consultant to evaluate our compensation programs.
ØNo Tax Gross-Ups – we do not provide our NEOs with any tax gross-ups.


How the amountsWe Determine and Assess Executive Compensation

Role of Independent Compensation Consultant.

To assist in evaluating our compensation formulas were determined, and how they fit into the Company's overall compensation objectives.

Generally, the amount of an executive's compensation is based in part on a determination of comparable compensation levels in the construction industrypractices and the personal judgement of the members of the Compensation Committee, drawing on their own business experience. For newly-employed executives, their prior salaries are also taken into account. The Committee attempts to set executives' salaries neither substantially higher nor substantially lower than the median in the industry.

Current Executive Officers.

Mr. Varello. Mr. Varello's nominal salary is unusual, and was adopted at his request to conserve the Company's cash resources and because of his faith in the future of the Company. His restricted stock award was made in lieu of a cash salary and was submitted to, and approved by, stockholders at the 2015 Annual Meeting.

Mr. Wadsworth. Mr. Wadsworth's salary is based on his prior salary as President of the Company's Ralph L. Wadsworth Construction Company, LLC subsidiary, increased to reflect his taking on additional responsibilities when he was promoted to Chief Operating Officer in March 2016.

Mr. Cutillo. Mr. Cutillo joined the Company as a vice president in October of 2015 at an initial salary of $275,000 that was subject to an increase to $300,000 upon completion of two short-term tasks related to his position as Vice President — Strategy & Business Development. He accomplished those tasks, and in May 2016, he was promoted to Executive Vice President & Chief Business Development Officer with expanded responsibilities and an increased annual salary of $325,000. In February 2017, Mr. Cutillo was elected President of the Company at an annual salary of $450,000. Mr. Cutillo's level of compensation was determined byprovided to our executives, the Compensation Committeecompensation committee from time to time retains an independent compensation consultant to provide advice and ongoing recommendations on these matters that are consistent with the assistance ofour business goals and pay philosophy. We believe that this input and advice produces more informed decision-making and assures that an outsideobjective perspective is considered in this important governance process. The compensation consultant,committee has retained Meridian Compensation Partners, LLC.

Mr. Ballschmiede. When he joined the Company, Mr. Ballschmiede'sLLC (Meridian) as its executive compensation was negotiated by him and the Compensation Committee using both comparable salaries in the industry for chief financial officers, and his extensive accounting and financial expertise and experience evidenced by his distinguished résumé.

Mr. Barzun. Mr. Barzun's salary was established in 2006 at $60,000 based on the fact that he would be serving on a part-time basis as the Company's General Counsel; by 2013, it had risen to its current level ($100,000) through merit increases as a result of increasing responsibilities.consultant. The Compensation Committee treats his salary as an annual retainer for the performance of routine matters, which, after the end of the year, is subject to increase by an amount that the Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Compensation Consultant — Independence. Meridian was first retained by the Compensation Committee in 2014 to provide advice on the design of a short- and long-term incentive compensation plan. In rendering services, Meridian, at that time and currently, reports directly to the Compensation Committee, and the Compensation Committee has the sole authority to retain or dismiss Meridian and to approve its fee arrangements. The Compensation Committeecommittee assessed theMeridian’s independence of Meridian pursuant to Securities and Exchange Commission rules, and concluded that itsMeridian’s work for the Compensation Committee diddoes not raise any conflictconflicts of interest.

- 25 -

Meridian has performed no servicesFor 2017, the scope of any kindMeridian’s engagement included providing market data which the committee referenced in evaluating 2017 compensation levels and assisting with the redesign of our compensation program structure for the Compensation Committee, the Board, or the Company other than as described above. Meridian's fees for this work, $23,278, was billed in 2017.

Compensation Consultant — Benchmarking2018.


Market Data and Peer Group.

In December 2016, Meridian was asked to benchmark the compensation of the position of president in contemplation of Mr. Cutillo's possible promotion.our executive officers as a reference for our committee to determine 2017 compensation levels. In seeking a useful peer group, the Compensation Committeecompensation committee and Meridian recognized that there are few publicly-traded companies in the heavy civil construction business that are close to the Company'scompany's size. Most other publicly-traded heavy civil construction companies are much larger than the Companycompany and are companies with which we rarely compete. Accordingly, we use a number of comparative factors incorporating financial, industry-specific, and both objective

23



and subjective elements to determine a group of appropriate firms for executive compensation benchmarking. The most common criterion for peer group inclusion is industry similarity. Other criterion includes similar business model, competition for business or executive talent, size (including revenue, market capitalization, assets, and geographic presence. Following this analysis, the Company rarely competes. Accordingly, the Compensation Committeecompensation committee decided to use the following peer group, which reflects companies with whicha median revenue that approximated our own (based on the Company competes for talent:

Additionally, Meridian provided supplemental market data from Equilar’s Top 25 Executive Compensation Survey for companies across a variety of industries with revenues between $500 million and $900 million (median of $692 million).

Role of Chief Executive Officer

Our chief executive officer makes recommendations to the compensation committee regarding the base salary and incentive compensation awards for our other executive officers, based on Meridian's analysis,his qualitative judgment regarding each officer’s individual performance, although the compensation committee makes all final compensation decisions regarding our executive officers. Our chief executive officer is not present when the compensation committee discusses or determines any aspect of his compensation.

Objectives of Our Compensation Committee set Mr. Cutillo's salary slightly below medianProgram

The compensation committee is responsible for designing, implementing, and administering our executive compensation program. The compensation committee seeks to increase stockholder value by:
rewarding past performance and incentivizing future performance;
fostering a culture of ownership;
providing a level of total compensation that will enable the company to attract and retain
talented executive officers; and
promoting sound compensation governance practices that encourage prudent decision-
making.

The compensation committee believes compensation should reward achievement of business performance goals, recognize individual initiative and leadership and link the interests of the peer group to reflectexecutives and stockholders.

2017 Executive Compensation Program

During 2017, our executive compensation program included two primary components: base salary and annual incentive awards payable in a combination of cash and equity.

After reviewing these components of our compensation program, the fact that he is a newly-elected President.

The results of the most recent stockholder advisory vote on executive compensation.

The Company conducts annual advisory votes on executive compensation. At the 2016 Annual Meeting, the vote was as follows:

Number of Shares
Entitled to Vote
Voted ForVoted AgainstAbstained
14,586,62313,640,928 (93.5%)509,528 (3.3%)436,167 (3.2%)

The Compensation Committee committee believes that this vote indicates general stockholder satisfaction with the Company's executive compensation policies and decisions. In the event that stockholders do not approve executive compensation for a given year, the Compensation Committee will review its decisions on compensation structure and levels, as well as the comparability of the executives' compensation to that of a peer group of companies before deciding whether to make any change in the compensation of one or more of the executives.

Incentive compensation arrangements for 2016. In February 2016, the Compensation Committee adopted an incentive compensation plan for executives and others. The 2016 Executive Incentive Compensation Program was a one-year plan that provided for establishing for participants as of the beginning of 2016 a target amount, which is the amount that can be earned by the participant if all the goals of the program were achieved in 2016. The target amount is expressed as a percent of the participant's base salary.

Under the plan, incentive compensation was earned based on the level of achievement of a Company earnings-per-share (EPS) goal for 2016 that accounted for 50% of incentive compensation and individual performance goals that accounted for the other half. In 2016, the EPS goal was not achieved. For participants in the Company's operating units, there was also an operating-unit goal based on the unit's earnings before interest and taxes (EBIT). In 2016, certain EBIT goals were achieved. The financial and individual performance goals of officers of the Company and of the chief executives of the Company's subsidiaries were subject to approval by the Compensation Committee.

Pursuant to the plan, payment of one-half of incentive compensation earned under the plan was made in cash, and one-half was made in the form of an award of shares of the Company's common stock that are subject to restrictions on their sale or other transfer and to forfeiture in certain circumstances, in order to align participants' interests with those of the Company's stockholders and serve to encourage participants to remain in the Company's employ. One executive officer, for personal reasons, was paid all in cash. The restrictions on the restricted stock lapse at the end of three years if the participant is then still an employee of the Company or operating unit, as the case may be.

- 26 -

If during 2016 a participant had resigned or his or her employment were terminated for cause, all benefits under the program would have been forfeited. If during 2016 a participant's employment were terminated without cause, for permanent disability, or because of the death of the participant, a pro-rated portion of earned program benefits would have been paid based on the financial results for the year, an assumption that the participant completed all individual performance goals satisfactorily, and the number of days during the year the participant was an employee.

The fact that the plan had no long-term goal reflects the Compensation Committee's view that in light of the volatility of the Company's common stock, a long-term goal, such as the total shareholder return goal that was a feature of the long-term element of the 2015 incentive compensation plan, would be unlikely to serve as an incentive to executives, who were fully concentrated on the short-term in furtherance of the Company's return to profitability.

Incentive compensation arrangements for 2017. In February 2017, the Compensation Committee adopted an executive incentive plan for 2017 that is essentially the same as the 2016 incentive plan except in certain respects. In the 2017 plan, the financial goal accounts for 75% of incentive compensation and individual performance goals account for 25%, reflecting the Compensation Committee's desire to put more emphasis on Company-wide financial performance. The restricted stock awards will vest annually in three installments, which the Compensation Committee believes has the same effect of aligning executives' financial interests with stockholders' interests, but serves as a more immediate incentive than the three year, so-call 'cliff vesting' of the 2016 plan.

For the same reasons described above for the 2016 plan, no long-term element was included in the 2017 plan. The Compensation Committee will consider adding a long-term goal to future incentive compensation plans when it believes that long-term goals can be reasonably established.

The following table shows some additional information about the participation of the named executive officers in the 2017 plan. As noted above, neither Messrs. Varello nor Barzun are participants in the plan.

Compensation Policies & Practices — Risk Management.

The Compensation Committee has reviewed the Company'srisks arising from our compensation policies and practices and in particular its incentive compensation and bonus policies, as they relate to risk management, and has determined that they support the Committee's compensation objectives without encouraging inappropriate, unintended, or excessive risk-taking byfor our employees, andincluding our executive officers, are not reasonably likely to have a material adverse effect on the Company.company. Further, the compensation committee believes that certain features of our compensation program, including our clawback, anti-hedging and anti-pledging policies, our stock ownership guidelines and our use of both cash- and equity-based awards, help to manage any compensation-related risks.


Base Salaries.

Our philosophy is that base salaries, which provide fixed compensation, should meet the objective of attracting and retaining the executive officers needed to manage our business successfully. Actual individual salary amounts reflect the compensation committee’s judgment with respect to each executive officer’s responsibility, performance, work experience and the individual’s historical salary level. As noted previously, during 2017 the company appointed a new chief executive officer and a new executive vice president & general counsel, and the compensation committee reviewed benchmarking data previously provided by Meridian to establish the appropriate levels of compensation for Messrs. Cutillo and Chandler. The Compensation Committee elected notcompensation committee also approved a modest increase to hire an outside adviserthe base salary of Mr. Ballschmiede during 2017. These changes are reflected in undertaking its risk review in 2016. For a full descriptionthe table below:

(1) Base salary amounts reflect each executive's designated base salary level as of the Company's significant risk factors, seeItem 1A. Risk Factors in the Company's 2016 Annual Report on Form 10-K, which is available with this Proxy Statement.

In reaching its conclusions, the Compensation Committee took into account many factors, including the fact that becauselast day of the naturerelevant calendar year, and include adjustments made during the calendar year. Amounts shown do not reflect the total base salary paid for such calendar year. The actual amount of base salary paid to each NEO during each relevant calendar year is listed on the "2017 Summary Compensation" table on page 29.


(2) Mr. Cutillo’s base salary was increased twice during 2017. Effective February 13, 2017, his base salary was increased to $450,000 upon his promotion to President of the Company's business, any short-term manipulationcompany, and then effective April 28, 2017, his base salary was increased to $550,000 in recognition of financial results will have an adverse effect over time,his promotion to chief executive officer.

(3) Mr. Chandler joined the company on October 12, 2017.    


Incentive Compensation Program.

Annual incentive awards represent variable components of compensation designed to reward our executive officers if the company achieves the established performance goal and if the executive achieves his or her individual performance goals, as follows:

Incentive compensation is paid in part in equity that vests over time, thereby subjecting the recipient's stock to extended market risk.
Officers of the Company and its subsidiaries are subject to stock retention requirements, which also subject their stockholdings to market risk.
There are appropriate caps on the amount of incentive compensation that can be earned.
Most of the Company's projects are performed over the course of more than one calendar year, so that a manipulated increase in profits in one year will have the effect of reducing profits in the subsequent year and vice versa.
The Company's claw-back policy applies to both cash and equity incentive compensation irrespective of whether or not the recipient ofapplicable. In February 2017, the compensation was at fault.

Percentage-of-Completion Accounting. The Compensation Committee considers that, by their nature,committee established the percentage-of-completion accounting and revenue recognition rules under which the Company is required to prepare its financial statements may be susceptible to manipulation. Percentage-of-completion accounting requires management to make estimates at least every month of the cost of completing projects that are on-going at the date of the review. These estimates directly affect reported profits, and profits, directly or indirectly, are the basisframework for the award of half or more of the Company's incentive compensation. The Compensation Committee believes that this risk is mitigated in the following ways:

Senior executives perform rigorous project reviews on a monthly basis to review estimates for any potential inaccuracies.
The Company's independent auditors review the current year's estimates and compare them to actual, prior-year results, so that over time, any manipulation of results should become evident.
As noted above, because most of the Company's large projects are performed over the course of more than one fiscal year, a manipulated increase in profits in one year will have the effect of reducing profits in the subsequent year, and vice versa.

- 28 -

The Total Stockholder Return Goal. Under the 2015 incentive compensation program, the long-term goal for the vesting of restricted stock units is based on the change in the Company's stock price over a period of three years (total shareholder return, or TSR) compared with the TSR of a peer group of companies over the same period. The Committee believes that manipulation of the Company's stock price to achieve this goal would be particularly difficult because the Company's small float makes the stock price susceptible to swings and variations unaffected by the Company's financial performance, and because of the unpredictability of the types of events and circumstances that actually affect the Company's stock price.

Employment Agreements of the Named Executive Officers. For the effects of the termination of employment of the named executive officers, see the section below entitledPotential

Payments upon Termination or Change-in-Control.

The following table shows the material financial features of the employment agreements or arrangements of the named executive officers for 2017. Messrs. Varello and Barzun do not participate in an incentive plan. Messrs. Cutillo, Wadsworth and Ballschmiede do not have employment agreements.

(1)Mr. Barzun's salary is subject to increase by an amount that the Compensation Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Mr. Varello. Mr. Varello entered into an employment agreement with the Company in March 2015 when he resigned as Chairman of the Board and ceased to be Chief Executive Officer of the Company on only an interim basis. The agreement expires on the third anniversary of its March 9, 2015 effective date. It provides for a salary of $1.00 per year and a single restricted stock award of 600,000 shares that vests in equal installments over three years. The award was approved by stockholders at the 2015 Annual Meeting. In place of participating in the Company's health plan, the agreement provides for the reimbursement of his out-of-pocket costs of maintaining the family health insurance coverage that he was maintaining prior to becoming Chief Executive Officer, and any replacement coverage that he may elect to obtain from time to time. He is also entitled to the use of a Company-owned vehicle.

Mr. Cutillo. Mr. Cutillo does not have an employment agreement. The basis for his salary as President is discussed above under the headingCompensation Discussion and Analysis — Current Executive Officers. In addition to his salary and participation in the 2017 executive incentive compensation plan, he is entitled to the use of a Company vehicle, the expenses of which are paid by the Company.

Mr. Ballschmiede. Mr. Ballschmiede does not have an employment agreement. He was hired on an at-will basis at an annual salary that is subject to annual reviews by the Chief Executive Officer, with any increase being subject to the approval of the Compensation Committee. In addition, upon becoming an employee, he was awarded 100,000 shares of restricted stock that vest in two equal annual installments.

- 29 -

Mr. Wadsworth. Mr. Wadsworth does not have an employment agreement. The basis for his salary is discussed above under the headingCompensation Discussion & Analysis — Current Executive Officers.

Mr. Barzun. Mr. Barzun's employment agreement became effective in March 2006 and continues until terminated by the Company or by Mr. Barzun. His salary is subject to annual merit increases. The Compensation Committee treats his salary as an annual retainer for the performance of routine matters, which, after the end of the year is subject to increase by an amount that the Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Potential Payments upon Termination or Change-in-Control. The table below describes the events that would trigger payments or the provision of other benefits to the named executive officers in the event of the termination of their employment or a change in control of the Company. The Company would provide all the payments and benefits described below. The amounts assume that the termination or change in control occurred on December 31, 2016.

Mr. Varello's employment agreement prohibits him from competing with the Company or soliciting its employees while employed by the Company and for eighteen months after his employment terminates. Messrs. Wadsworth, Ballschmiede and Barzun are not subject to those prohibitions. Mr. Varello's employment agreement also prohibits him indefinitely from disclosing the Company's confidential information.

At December 31, 2016 the closing price of the Company's common stock was $8.46 per share. Accordingly, the total market value of the shares subject to restrictions that would have vested in a change in control of the Company on December 31, 2016 are as follows:

Mr. Varello                  $3,384,000

Mr. Cutillo                   $211,500

Mr. Ballschmiede        $423,000

Messrs. Wadsworth and Barzun held no restricted stock at December 31, 2016.

The accounting for stock awards is described in the Notes to Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2016.

In the case of awards for 2016, the dollar amount represents incentive compensation paid in shares of restricted common stock under the Company's 2016 Executive Incentive Compensation Program.program. Under the program, the incentive awards for our NEOs could be earned based on the following: 75% of the award is based on the company’s achievement of


25



earnings per share (EPS) of $0.18 (the target), and 25% is based on the executive’s attainment of pre-established individual performance goals. Of our NEOs, only Messrs. Cutillo, Ballschmiede and Wadsworth participated in the program for 2017, and each was assigned a target award level based on a percentage of his base salary received during 2017, as described below:

Name Annual Base Salary

Mr. Ballschmiede...... $439,874 170% 75% $560,839 25% $186,946
Mr. Wadsworth......... $425,000 170% 75% $541,875 25% $180,625
With respect to the EPS goal, the committee established threshold (80% of target) and maximum (120% of target) goals as well, and executives could earn between 80% and 120% of the applicable target award based on the level of achievement of the EPS goal. With respect to the individual performance goals, the executives could earn no more than 100% of the applicable target award based on performance. The pre-established individual performance goals, which represented 25% of the target award, varied by executive, and included the following: completion of strategic acquisitions, ensuring that the company’s strategic plan and budget are fully developed, presented and implemented, cost reductions, and succession planning.

Payment of one-half of any incentive compensation earned under the program is made in cash, and one-half is made in the form of an award of time-based restricted stock units (RSUs) that are subject to a three-year vesting period, with one-third of the RSUs vesting on January 1, 2019 and on each of the next two anniversaries thereof. The number of sharesRSUs is calculateddetermined using the simple average of the closing prices of the Company's common stock in December 2016.

2017.

In March 2018, the compensation committee met and determined that the Company had achieved EPS in the amount of $0.43, which resulted in 120% payout of this EPS component. In addition, the compensation committee evaluated the performance of each of the NEOs relative to the individual performance goals set for each, and determined that each executive had achieved the individual goals as reflected in the table below. As a result, in March 2018, the compensation committee approved the following payouts to the NEOs:

Changes to Incentive Compensation Program for 2018

In January 2018, the compensation committee approved a new senior executive incentive compensation plan. The plan, which is effective for fiscal years beginning in 2018, consists of an annual incentive program, which is referred to as the Short-Term Incentive, or STI, and a three-year incentive program, which is referred to as the Long-Term Incentive, or LTI. The STI and the LTI are performance driven programs, and reflect the pay-for-performance philosophy of the company by linking the opportunity to earn additional compensation to the achievement of short-term and long-term company financial and strategic goals.

This new program differs from the company’s prior program in the following ways:
It provides that payout of the short-term incentive award will be made solely in cash.
It establishes a separate long-term incentive program with a three-year performance cycle.
The long-term incentive awards will be delivered in the form of a time-based RSU grant (representing 50% of the target value) and a performance share unit (representing 50% of the target value), which will be earned based on achievement of an EPS goal over the performance cycle.

Clawback Policy
The company's clawback policy applies to all incentive compensation paid to an employee, including our executive officers (whether paid in cash or in equity) that was based on financial statements that are subsequently restated. Following such a restatement, the compensation shall be adjusted, if necessary, so that the employee will have received no more and no less than the amount that he or she would have received had the incentive award been calculated based on the restated financial results. The policy applies regardless of the employee’s culpability or fault with respect to the error, event, act or omission that caused the restatement.

Stock Ownership Guidelines

We encourage stock accumulation because we believe that it is important for our executive officers to align their interests with the long-term interests of our stockholders. Accordingly, our board of directors adopted stock ownership guidelines applicable to our executive officers. Under the guidelines, each of our executive officers is encouraged to maintain ownership of shares of our common stock valued at five times (for our CEO) or three times (for our other executive officers) his or her base salary. Shares of our common stock owned individually or jointly, shares held by members of the executive’s immediate family or by a trust for the executive or his immediate family, as well as shares subject to unvested restricted stock and RSUs are counted for purposes of the stock ownership guidelines.

Our executive officers have five years from the date of their respective appointments (or from January 17, 2018, the date upon which the guidelines were revised, whichever is later) to attain these ownership levels. Until the specified ownership levels are met, our executive officers are expected to retain 75% of the net shares issued upon the vesting of equity awards granted by the company, after deducting any shares used to pay applicable taxes. All of our executive officers are currently in compliance with the guidelines, and as they have all been in their respective positions with the company for less than three years, each has until January 17, 2023 to reach his target ownership level.

Limited Executive Perquisites and No Special Retirement Benefits
We seek to maintain a cost conscious culture in connection with the benefits provided to our executive officers. As a result, we provide limited perquisites to our executive officers. Please see “Executive Compensation Tables—2017 Summary Compensation Table” for a description of the perquisites provided in 2017.

Retirement benefits fulfill an important role within our overall executive compensation objectives by providing a financial security component, which in turn promotes retention. However, our executive officers do not receive any retirement benefits that are not generally available to our other full-time employees. We maintain a 401(k) plan, a tax-qualified defined contribution retirement plan in which our executive officers are eligible to participate, which currently provides a 5% employer match. We do not maintain any excess benefit plans, defined benefit or pension plans, or any deferred compensation plans.

27



No Cash Severance and Change of Control Benefits

We currently do not have employment agreements with any of our executive officers, nor do we have any agreements or plans in place providing for cash payments in connection with a termination of employment or a change of control transaction. However, the terms of our outstanding restricted stock awards provide that vesting of the award will be accelerated in connection with certain terminations of employment and also upon the occurrence of a qualifying change of control.

The value of the potential acceleration of outstanding restricted stock awards as of December 31, 2017 under these scenarios is more fully described in “Potential Payments upon Termination or Change in Control” on page 33.

Tax and Accounting Considerations

The accounting and tax treatment of compensation generally has not been a factor in determining the amounts of compensation awarded to our executive officers. However, the compensation committee and management have considered the accounting and tax impact of various program designs to balance the potential cost to the company with the benefit or value to the executive officer.

Compensation Committee Report
The compensation committee of the board has reviewed and discussed with management the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K, and based on such review and discussion, the compensation committee recommended to the board that the Compensation Discussion and Analysis be included in this proxy statement.

100% achievementFor 2017, under our incentive compensation program, Messrs. Cutillo, Ballschmiede and Wadsworth had a target award based on a multiple of salary, with the amount to be earned based on (a) the company’s performance relative to a pre-established EPS target (representing 75% of the target award), and (b) the executive’s performance relative to pre-established individual performance goals which was(representing 25% of the target award). The amounts reported represent the estimated threshold, target and maximum possible incentive payments that could have been earned even if in some manner the actual achievement level were higher than 100%.
(2)Stock Vested for 2016. The following table shows information forreceived by each named executive officer holdingpursuant to the program for 2017. The estimated amounts in the “Target” column were approved by the compensation committee and reflect 195% of base salary for Mr. Cutillo, and 170% of base salary for each of Mr. Ballschmiede and Mr. Wadsworth. The estimated amounts in the “Threshold” column reflect achievement of the threshold level of performance relative to the EPS target, resulting in a payout of 80% of the target award for that component, and 0% achievement on the individual component, as there is no minimum level required for payout. The estimated amounts in the “Maximum” column reflect achievement of the maximum level of performance relative to the EPS target, resulting in a payout of 120% of the target award for that component, and a payout of 100% of target award on the individual component, as that is the maximum that can be earned under that component. Under the terms of the program as approved by the compensation committee in February 2017, any earned award will be paid 50% in cash and 50% in RSUs that will vest in one-third increments on the first three anniversaries of the grant date, with the number of RSUs determined using the simple average of the closing prices of our common stock in December 2017.

PERFORMANCE GRAPH

The following graph compares the percentage change in the Company's cumulative total stockholder return on its common stock for the last five years with the Dow Jones US Index, a broad market index, and the Dow Jones US Heavy Construction Index, a group of companies whose marketing strategy is focused on a limited product line, such as civil construction. Both indices are published in The Wall Street Journal. The returns are calculated assuming that an investment with a value of $100 was made in the Company's common stock and in each index at the end of 2010, and that all dividends were reinvested in additional shares of common stock, although the Company has paid no dividends during the periods shown. The graph lines merely connect the measuring dates, and do not reflect fluctuations between those dates. The stock performance shown on the graph is not intended to be indicative of future stock performance.

No named executive officer exercised options during 2017 and there are no outstanding option awards.

(2)
The value realized on vesting of restricted stock is based on the closing sale price on the date of vesting of the restricted stock or, if there were no reported sales on such date, on the last preceding date on which any reported sale occurred.

Potential Payments upon Termination or Change in Control
We do not have any employment agreements or change of control plans or agreements with any of our current executive officers that provide for payments or benefits upon a termination of employment or a change of control. Pursuant to the terms of our stock incentive plan and the restricted stock agreements thereunder, upon a (i) termination of employment as a result of death, permanent disability, or by the company without cause, or (ii) a change of control of the company, all outstanding restricted stock awards vest.
For purposes of the restricted stock awards, “cause” is generally defined as (i) gross negligence in the performance of the executive’s duties, (ii) commission of an act of theft or other dishonesty, (iii) conviction of any other criminal activity (other than a traffic violation or minor misdemeanor), (iv) participation in any activity involving moral turpitude that is, or could reasonably be expected to be, injurious to the business or reputation of the company, (v) use of alcohol immoderately and/or use of non-prescribed narcotics that have the effect of adversely and materially affecting the performance of the executive’s duties, or (vi) a material breach of company policy.    
The following table sets forth the restricted stock awards for each of our named executive officers (other than Messrs. Varello and Barzun) that would vest as a result of a change of control, or due to a termination of employment due to death, permanent disability, or a termination by the company without cause occurring on December 31, 2017. To calculate the value of the awards, we have used the closing price of our

common stock of $16.28 on December 29, 2017, as reported on NASDAQ. The table does not include amounts that may be payable under our 401(k) plan or other benefits payable to all company employees.

Separation of Mr. Varello
Mr. Varello was chief executive officer of the company until April 28, 2017. In connection with Mr. Varello’s resignation as an officer, 200,000 shares of unvested restricted stock vested. These shares are reflected in the "2017 Stock Vested" table on page 32. Upon his retirement from our board on December 31, 2017, 5,257 shares of restricted stock granted in 2017 as part of his compensation as a director were forfeited.

Separation of Mr. Barzun
Mr. Barzun was senior vice president and general counsel, secretary of the company until October 27, 2017. Based on the circumstances of his departure, Mr. Barzun was entitled to receive the payments and benefits due to him upon a termination of employment without cause under his employment agreement with the company. These benefits include (i) continuation of his annual salary for a period of 12 months and (ii) reimbursement of COBRA premiums for a period of 12 months. Mr. Barzun also received a bonus of $150,000 for 2017, $125,000 of which was paid within 30 days of termination, with the balance of $25,000 payable on or before May 2, 2018, provided Mr. Barzun complies with certain restrictive covenants. These amounts are reflected in the "2017 Summary Compensation" table on page 29.

Pay Ratio

The following is a reasonable estimate, prepared under applicable SEC rules, of the ratio of the annual total compensation of Mr. Cutillo, our current chief executive officer, to the median of the annual total compensation of our other employees. We determined our median employee based on W-2 earnings for 2017 (annualized in the case of full- and part-time employees who joined the Company during 2017) of each of our 1,684 employees (excluding the chief executive officer) as of December 18, 2017. The annual total compensation of our median employee for 2017 was $48,625. As disclosed in the "2017 Summary Compensation" table appearing on page 29, Mr. Cutillo’s annual total compensation for 2017 was $2,134,693. However, as Mr. Cutillo became our chief executive officer on April 28, 2017, for purposes of calculating the CEO pay ratio we annualized Mr. Cutillo’s base salary as chief executive officer for the Review, full year in accordance with SEC rules, resulting in annual total compensation of $2,181,419. Based on the foregoing, our estimate of the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all other employees was 45 to 1. Given the different methodologies that various public companies will use to determine an estimate of their pay ratio, the estimated ratio reported above should not be used as a basis for comparison between companies.

Proposal No. 2: Advisory Vote on the Compensation of Our Named Executive Officers

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), enacted in July 2010, requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our NEOs as disclosed in this proxy statement in accordance with Section 14A of the Securities Exchange Act of 1934. This vote (commonly referred to as a “say-on-pay” vote) is advisory, which means that it is not binding on the company, the board of directors or the compensation committee of the board of directors. However, our board and the compensation committee value the opinion of our stockholders and will consider the outcome of the vote when evaluating our executive compensation program. The vote is not intended to address any specific compensation arrangement or amount, but rather the overall compensation of our NEOs and our compensation philosophy and practices as disclosed under the “Executive Officer Compensation” section of this proxy statement. This disclosure includes the compensation tables and narrative discussion following the compensation tables.

At last year’s annual meeting, we provided our stockholders with the opportunity to cast a non-binding advisory vote regarding the compensation of our named executive officers as disclosed in our proxy statement for the 2017 annual meeting of stockholders. Our stockholders approved the “say-on-pay” proposal by greater than 90% of the voting power of the outstanding shares of our common stock present, in person or by proxy, at the 2017 annual meeting and entitled to vote. Last year, we also asked our stockholders to vote on whether we should hold a “say-on-pay” vote every one, two or three years. Consistent with the recommendation of our board, our stockholders voted to hold the “say-on-pay” vote every year, with over 75% of the total votes cast voting in favor of holding an annual “say-on-pay” vote. After consideration of the 2017 voting results, and based upon its prior recommendation, our board elected to hold “say-on-pay” votes on an annual basis until the next advisory vote on the frequency of future “say-on-pay” votes, which will be held no later than our 2023 annual meeting of stockholders. Accordingly, this year we are again asking our stockholders to vote on the following resolution:

RESOLVED, that the stockholders of Sterling Construction Company, Inc. (the “Company”)
approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s proxy statement for the 2018 annual meeting of stockholders pursuant to Item 402 of Regulation S-K of the rules of the Securities and Exchange Commission.

In considering how to vote on this proposal, we encourage you to review the relevant disclosures in this proxy statement, especially the Compensation Discussion and Analysis, which contain detailed information about our executive compensation program.

Vote Required to Approve, on an Advisory Basis, the Compensation of Our Named Executive Officers

Approval of this proposal requires the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy and entitled to vote on the proposal. For more information on the voting requirements, see “Questions and Answers about the Proxy Materials, Annual Meeting and Voting.”

Recommendation of the Board of Directors

OUR BOARD RECOMMENDS THAT YOU VOTE FOR THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

Audit Committee Report

The audit committee is currently composed of four directors, Milton L. Scott (chairman), Maarten D. Hemsley, Raymond F. Messer and Richard O. Schaum, all of whom are independent, as defined by SEC rules and in the NASDAQ listing standards. In addition, the board has determined that each of Messrs. Hemsley and Scott qualifies as an “audit committee financial expert,” as such term is defined by the rules of the SEC. We operate under a written charter approved by us and adopted by the board of directors. Our primary function is to assist the board of directors in fulfilling the board’s oversight responsibilities relating to (1) the effectiveness of the company’s internal control over financial reporting, (2) the integrity of the company’s financial statements, (3) the company’s compliance with legal and regulatory requirements, (4) the qualifications and independence of the company’s independent registered public accounting firm, (5) the performance of the company’s independent registered public accounting firm and (6) the review and approval or ratification of any transaction that would require disclosure under Item 404(a) of Regulation S-K of the Exchange Act.
We oversee the company’s financial reporting process on behalf of the board. Our responsibility is to monitor this process, but we are not responsible for developing and consistently applying the company’s accounting principles and practices, preparing and maintaining the integrity of the company’s financial statements and maintaining an appropriate system of internal controls, auditing the company’s financial statements and the effectiveness of internal control over financial reporting, or reviewing the company’s unaudited interim financial statements. Those are the responsibilities of management and the company’s independent registered public accounting firm, respectively.
During 2017 management assessed the effectiveness of the company’s system of internal control over financial reporting in connection with the company’s compliance with Section 404 of the Sarbanes-Oxley Act of 2002. We reviewed and discussed with management and Grant Thornton LLP (“Grant Thornton”), the company’s independent registered public accounting firm, management’s report on internal control over financial reporting and Grant Thornton’s report on their audit of the company’s internal control over financial reporting as of December 31, 2017, both of which are included in our 2017 annual report.

Appointment of Independent Registered Public Accounting Firm; Financial Statement Review
In March 2017, in accordance with our charter, we appointed Grant Thornton as the company’s independent registered public accounting firm for 2017. We have reviewed and discussed the company’s audited financial statements for 2017 with management and Grant Thornton. Management represented to us that the audited financial statements fairly present, in all material respects, the financial condition, results of operations and cash flows of the company as of and for the periods presented in the financial statements in accordance with accounting principles generally accepted in the United States, and Grant Thornton provided an opinion to the same effect.
We have received from Grant Thornton the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board (PCAOB) regarding the independent accountant’s communications with the audit committee concerning independence, and we have discussed with Grant Thornton their independence from the company and management. We have also discussed with Grant Thornton the matters required to be discussed by PCAOB Auditing Standard No. 1301 – Communications with Audit Committees (PCAOB Release No. 2012-004, August 15, 2012), effective pursuant to SEC Release No. 34-68453 (December 17, 2012).
In addition, we have discussed with Grant Thornton the overall scope and plans for their audit, and have met with them and management to discuss the results of their examination, their understanding and evaluation of the company’s internal controls as they considered necessary to support their opinion on the financial statements for the year 2017, and various factors affecting the overall quality of accounting principles applied in the company’s financial reporting. Grant Thornton also met with us without management being present to discuss these matters.


35



In reliance on these reviews and discussions, we recommended to the board of directors, and the board of directors approved, the inclusion of the audited financial statements referred to above in the 2017 annual report.

We incurred these audit-related fees for a due diligence project on a target company in 2016, and for due diligence related to our new credit facility in 2017.
————————
The audit committee has determined that the provision of the services described above is compatible with maintaining the independence of our independent registered public accounting firm.

Pre-Approval Policies and Procedures
The audit committee’s policy is to pre-approve all audit services, audit-related services and other services provided by our independent registered public accounting firm. In accordance with that policy, the committee annually pre-approves a list of specific services and categories of services, including audit, audit-related and other services, for the upcoming or current fiscal year, subject to specified cost levels. All requests for services to be provided by the Company’s independent registered public accounting firm must be submitted to the Company’s chief financial officer and the chair of the audit committee, together with a detailed description of the services to be rendered. The chief financial officer may authorize any services that have been pre-approved by the audit committee. Any service that is not included in the approved list of services must be separately pre-approved by the audit committee. In addition, if fees for any service exceed the amount that has been pre-approved, then payment of additional fees for such service must be specifically pre-approved by the audit committee. During 2017, none of the services provided by our independent registered public accounting firm required use of the de minimis exception to pre-approval contained in the SEC’s rules.

Proposal No. 3: Ratification of Transactionsthe Appointment of Our Independent Registered Public Accounting Firm

In March 2018, in accordance with Related Persons.

Generalour charter, we appointed Grant Thornton as the company’s independent registered public accounting firm for 2018. Our board and the audit committee seek stockholder ratification of the audit committee’s appointment of Grant Thornton as our independent registered public accounting firm to audit our and our subsidiaries’ financial statements for the year 2018. If our stockholders do not ratify the appointment of Grant Thornton, the audit committee will reconsider this appointment. Representatives of Grant Thornton are expected to be present at the meeting to respond to appropriate questions, and those representatives will also have an opportunity to make a statement if they desire to do so.

Vote Required to Ratify the Appointment of our Independent Registered Public Accounting Firm
Approval of this proposal requires the affirmative vote of a majority of the shares of our common stock present in person or by proxy and entitled to vote on the proposal. For more information on the voting requirements, see “Questions and Answers about the Proxy Materials, Annual Meeting and Voting.”
Recommendation of the Board of Directors
OUR BOARD RECOMMENDS THAT YOU VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Proposal No. 4: Adoption of the 2018 Stock Incentive Plan

Our board of directors unanimously approved, and recommends that our stockholders adopt, the 2018 Stock Incentive Plan (the Plan), which is summarized below and attached as Annex A to this proxy statement. Because this is a summary, it does not contain all of the information that may be important to you. You should read Annex A carefully before you decide how to vote.
Why Stockholders Should Vote to Adopt the Plan:

EquityIncentiveAwardsAreAnImportantPartOfOurCompensationPhilosophy
The company believes that the adoption of the Plan is essential to our success. The Plan is intended to increase stockholder value and advance the interests of the company and its subsidiaries by furnishing a variety of equity incentives designed to (a) attract, retain, and motivate key employees, officers, and directors of the company and consultants and advisers to the company and (b) strengthen the mutuality of interests among such persons and the company’s stockholders. The board and company management believe that equity incentives are necessary to remain competitive in the industry.

OurCurrent Plan Has Insufficient SharesAvailableForGrant
There are currently less than 20,000 shares remaining available for future grants to our officers, employees and non-employee directors under our current stock incentive plan. As such, we will not have sufficient shares available to make long-term incentive grants to our executive officers and key employees in the future, nor do we have sufficient shares to make our annual equity grant to our non-employee directors in May 2018. While the company could increase cash compensation if it is unable to grant equity incentives, replacing equity awards with cash awards would not only misalign our executive and stockholder interests, it would also increase cash compensation expense and divert cash that could otherwise be reinvested in our business.

We have a History of Prudent Use of Shares
In determining to adopt the Plan, we considered the following:
Share Reserve. The Board'sboard has approved the reservation of 1,800,000 shares under the Plan. If the Plan is approved by our stockholders, no new grants will be made under our current stock incentive plan.
Burn Rate. Our annual burn rate for each of calendar years 2015, 2016 and 2017 was 5.1%, 0.3% and 0.8%, respectively, resulting in a three-year average burn rate of 2.1%. Annual equity burn rate is calculated by dividing (1) the number of shares subject to equity awards granted during the year by (2) the weighted-average number of shares outstanding at the end of the applicable year.
Expected Duration of the Plan. The company expects the share reserve under the Plan to provide the company with enough shares for awards for approximately four to five years, assuming the company continues to grant awards consistent with its current practices and historical usage, as reflected in its average three-year burn rate, and noting that future circumstances may require the company to change its current equity grant practices. As the company cannot predict its future equity grant practices with any degree of certainty at this time, the share reserve under the Plan could last for a shorter or longer time.
Dilution. In calendar years 2015, 2016 and 2017, the end of year overhang rate (calculated by dividing (1) the sum of the number of shares issuable pursuant to equity awards outstanding at the end of the calendar year plus shares remaining available for issuance for future awards at the end of the calendar year by (2) the sum of the number of shares outstanding at the end of the calendar year plus the sum of (1) above) was 3.2%, 2.2% and 1.5%, respectively. Upon adoption of the Plan, the company expects its overhang to be approximately 7.3%.
In light of the factors described above, the board has determined that the size of the share reserve under the Plan is reasonable and appropriate at this time.

38



Equity Compensation Best Practices Reflected in the Plan

The Plan has a number of provisions that the company believes are consistent with best practices in equity compensation, protect stockholder interests and promote effective corporate governance, including the following:

Stockholder Approval is Required for Additional Shares and Other Material Amendments. The Plan does not contain an annual “evergreen” provision. The Plan authorizes a limited number of shares, and stockholder approval is required to increase the maximum number of shares of common stock which may be issued under the Plan. In addition, other material amendments to the Plan require stockholder approval.
No Discount Stock Options or Stock Appreciation Rights. All stock options and stock appreciation rights will have an exercise price equal to or greater than the fair market value of the company’s common stock on the date the stock option or stock appreciation right is granted; although discount stock options and SARs may be granted in the event such awards are assumed or substituted in connection with certain corporate transactions. For purposes of equity awards, we generally define fair market value as the closing sale price of a share of our common stock on the stock exchange or national market system on which our common stock is listed on such date or, if no sale occurred on the date in question, the closing sale price for a share of our common stock on the last preceding date for which such quotation exists. The closing sale price for a share of our common stock on the NASDAQ, on March 13, 2018 was $13.01.
Administration by Independent Directors. Awards under the Plan are administered by the compensation committee which is an independent committee of our board.
Limitations on Dividend Payments. Dividends and dividend equivalents may accrue on awards, but will only pay out if the applicable vesting conditions are met. Further, participants holding stock options or stock appreciation rights do not receive dividend equivalents for any period prior to the exercise of the award.
Limitations on Grants. Individual limits on awards granted to any participant pursuant to the Plan during any calendar year apply as follows: (a) except for non-employee directors, a maximum of 500,000 shares of common stock may be subject to awards granted to a participant; and (b) with respect to non-employee directors, the aggregate grant date fair value of awards under the Plan granted to a director in a calendar year may not exceed $300,000. These amounts may be adjusted to take into account equity restructurings and certain other corporate transactions as described below.
No Repricing of Awards. Awards may not be repriced, replaced or regranted through cancellation or modification without stockholder approval if the effect would be to reduce the exercise price for the shares under the award.
No Tax Gross-Ups. The Plan does not provide for any tax gross-ups.
No Liberal Share Counting. Shares of common stock delivered or withheld in payment of the exercise price of a stock option or SAR, delivered or withheld to satisfy tax obligations in respect of an award, or repurchased with the proceeds of an option exercise may not be re-issued under the Plan.
Minimum Vesting Conditions. All awards are subject to a minimum one-year vesting requirement, except that up to 90,000 shares (5% of the shares available under the Plan) may be granted without compliance with this minimum vesting condition.
Clawback of Awards. All Awards (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to the company clawback policy on transactions betweenimplemented to comply with Applicable Laws, including any clawback policy adopted to comply with the CompanyDodd-Frank Wall Street Reform and related persons isConsumer Protection Act and any rules or regulations promulgated thereunder, as set forth in such a clawback policy or the written charterAward Agreement.
Other company policies that help align the interests of our directors and executive officers with those of our stockholders include our policies that prohibit our directors and executive officers from hedging our common stock, and our minimum stock ownership guidelines for our directors and executive officers. See

“Board Governance – Director and Executive Officer Stock Ownership Guidelines” and “Executive Officer Compensation – Compensation Discussion and Analysis.”

Summary of the Audit Committee. 2018 Stock Incentive Plan

Administration. The policy requirescompensation committee of our board of directors will have plenary authority to administer the Audit CommitteePlan and has authority to reviewmake awards under the Plan and to set the terms of the awards.
References herein to the “committee” refer to the compensation committee. Subject to the limitations specified in advancethe Plan, the compensation committee may delegate its authority to appropriate officers of the company with respect to grants to employees or consultants who are not subject to Section 16 of the Securities Exchange Act of 1934.
Eligible Participants. Our officers, directors and employees and our consultants and advisors will be eligible to receive awards, or incentives, under the Plan when designated as Plan participants. We currently have four executive officers and six non-management directors eligible to receive awards under the Plan. In addition, six other employees currently participate in our long-term incentive program, and a total of 533 other employees would be eligible to receive awards under the Plan.

Awards. Awards under the Plan may be granted in any one or a combination of the following forms:
for officers and employees only, incentive stock options under Section 422 of the Internal Revenue Code (ISOs);
non-qualified stock options;
stock appreciation rights (SARs);
restricted stock;
restricted stock units (RSUs); and
other stock-based awards.
Authorized Shares. The Plan authorizes the issuance of up to 1,800,000 shares of common stock, all of which can be issued pursuant to the exercise of ISOs under the Plan during its ten-year term. Shares issued under the plan may be authorized but unissued shares, shares purchased on the open market or treasury shares.
Limitations and Adjustments to Shares Issuable Through the Plan. Awards for no more than 500,000 shares may be granted to a participant in a single year, however, with respect to non-employee directors, the aggregate grant date fair value of awards under the Plan granted to a director in a calendar year may not exceed $300,000.
Generally, for purposes of determining the maximum number of shares of our common stock available for delivery under the Plan, shares that are not delivered because an award is forfeited, cancelled, or settled in cash will not be deemed to have been delivered under the Plan. With respect to SARs paid in shares, all shares to which the SARs relate are counted against the Plan limits rather than the net number of shares delivered upon exercise. If shares are withheld to satisfy the exercise price of a stock option or SAR or the tax withholding obligation associated with any award, those withheld shares will not be available for reissuance under the Plan. In addition, shares purchased on the open market with the proceeds of an option exercise will not be available for reissuance under the Plan.
Proportionate adjustments will be made to all of the share limitations provided in the Plan, including shares subject to outstanding awards, in the event of any recapitalization, reclassification, stock dividend, stock split, combination of shares or other change in the shares of our common stock. Further, the committee may adjust the terms of any award to the extent appropriate to provide participants with the same relative rights before and after the occurrence of any such event.
Minimum Vesting Requirements. All awards granted under the Plan must be made subject to a one-year vesting period, although this minimum vesting requirement does not apply to awards with respect to five percent of the shares authorized under the Plan.

40



Amendments to the Plan. The board may amend or discontinue the Plan at any time. However, our stockholders must approve any amendment that would:
materially increase the benefits accruing to participants under the Plan;
increase the number of shares of common stock that may be issued under the Plan;
materially expand the classes of persons eligible to participate in the Plan;
expand the types of awards available for grant under the Plan;
materially extend the term of the Plan;
materially change the method for determining the exercise price of a stock option or SAR; or
permit the re-pricing of a stock option or SAR.
No amendment or discontinuance of the Plan may materially impair any previously granted award without the consent of the recipient.
Term of the Plan. No awards may be granted under the Plan after May 2, 2028.
Types of Incentives. Each of the types of incentives that may be granted under the Plan is described below:
Stock Options. The committee may grant non-qualified stock options or ISOs to purchase shares of our common stock. The committee will determine the number and exercise price of the options, provided that the option exercise price may not be less than the fair market value of a share of common stock on the date of grant, except for an option granted in substitution of an outstanding award in an acquisition transaction. In addition, the committee will determine the time or times that the options become exercisable, provided that options are subject to the minimum vesting requirement and exception described above. The term of an option will also be determined by the committee, but may not exceed ten years from the date of the grant. As noted above, the committee may not, without the prior approval of our stockholders, decrease the exercise price for any outstanding option after the date of grant. In addition, an outstanding option may not, as of any date that the option has a per share exercise price that is greater than the then current fair market value of a share of common stock, be surrendered to us as consideration for the grant of a new option with a lower exercise price, another incentive, a cash payment or shares of common stock, unless approved by our stockholders. ISOs will be subject to certain additional requirements necessary in order to qualify as incentive stock options under Section 422 of the Internal Revenue Code. In addition, participants holding stock options will not be entitled to any dividend equivalent rights for any period of time prior to exercise of the stock option.
Stock Appreciation Rights. A stock appreciation right is a right to receive, without payment to us, a number of shares of common stock or an amount of cash determined by dividing the product of the number of shares as to which the SAR is exercised and the amount of the appreciation in each share by the fair market value of a share on the date of exercise of the right. The committee will determine the exercise price used to measure share appreciation, provided that the exercise price may not be less than the fair market value of a share of common stock on the date of grant, except for a SAR granted in substitution of an outstanding award in an acquisition transaction. In addition, the committee will determine whether the right may be paid in cash, shares of common stock, or a combination of the two, and the number and term of SARs, provided that the term of a SAR may not exceed ten years from the date of grant. SARs are subject to the minimum vesting requirement and exception described above. The Plan restricts decreases in the exercise price and certain exchanges of SARs on terms similar to the restrictions described above for stock options. Participants holding SARs will not be entitled to any dividend equivalent rights for any period of time prior to exercise of the SAR.
Restricted Stock. Shares of common stock may be granted by the committee and made subject to restrictions on sale, pledge or other transfer by the recipient for a certain restricted period. All shares of restricted stock will be subject to such restrictions as the committee may provide in an agreement with the participant, provided that the minimum vesting requirements described above are satisfied. Subject to the restrictions provided in the agreement and the Plan, a participant receiving restricted stock shall have all of the rights of a stockholder as to such shares, including the right to accrue dividends if provided for in the agreement. Notwithstanding the previous sentence, any and all cash and stock dividends paid with respect to the shares of restricted stock will be subject to the same

41



vesting and forfeitability conditions, including attainment of any performance goals, as are applicable to the underlying shares of restricted stock.
Restricted Stock Units. A restricted stock unit represents the right to receive from the company on the scheduled vesting date or other specified payment date one share of common stock. All RSUs will be subject to such restrictions as the committee may provide in an agreement with the participant, provided that the minimum vesting requirements described above are satisfied. Subject to the restrictions provided in the agreement and the Plan, a participant receiving RSUs shall have no rights of a stockholder as to such units until such time as shares of common stock are issued to the participant. RSUs may be granted with dividend equivalent rights; provided, however, that any and all dividend equivalent rights with respect to the RSUs will be subject to the same vesting and forfeitability conditions, including attainment of any performance goals, as are applicable to the underlying RSUs.
Other Stock-Based Awards. The Plan also permits the committee to grant participants awards of shares of common stock and other awards that are denominated in, payable in, valued in whole or in part by reference to, or are otherwise based on the value of, or the appreciation in value of, shares of common stock (other stock-based awards). The committee has discretion to determine the times at which such awards are to be made, the size of such awards, the form of payment, and all other conditions of such awards, including any restrictions, deferral periods or performance requirements, provided that the minimum vesting requirements described above are satisfied. Other stock-based awards may be granted with dividend equivalent rights; provided, however, that any and all dividend equivalent rights with respect to the award will be subject to the same vesting and forfeitability conditions, including attainment of any performance goals, as are applicable to the underlying award.

Clawback. The Plan also provides that all Awards (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to the company clawback policy implemented to comply with Applicable Laws, including any clawback policy adopted to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, as set forth in such a clawback policy or the Award Agreement.

Termination of Employment; Change of Control. If a participant ceases to be an employee of the company or to provide services to us for any reason, including death, disability, or retirement, the participant’s outstanding awards may be exercised, shall vest or shall expire at such time or times as may be determined by the committee and described in the award agreement.
Unless otherwise provided in an award agreement, upon a change of control: (a) all options and SARs will become immediately exercisable, (b) all time-vested restrictions on restricted stock, RSUs or other stock-based awards will lapse, and (c) all performance measures applicable to awards will be disregarded and the award will vest at the target payout level. Further, in the event of a change of control, the committee may, in its sole and absolute discretion and authority, without obtaining the approval or consent of the company’s stockholders or any participant with respect to his or her outstanding awards, take one or more of the following actions:
arrange for or otherwise provide that each outstanding award shall be assumed or a substantially similar award shall be substituted by a successor corporation or a parent or subsidiary of such successor corporation;
require that all outstanding options and SARs be exercised on or before a specified date (before or after such change of control) fixed by the committee, after which specified date all unexercised options and SARs shall terminate;
arrange or otherwise provide for payment of cash or other consideration to participants representing the value of such awards, if any, in exchange for the satisfaction and cancellation of outstanding awards, or cancel any outstanding awards for no payment if the award has no value; or
make other appropriate adjustments or modifications.



42



Transferability of Awards. Awards under the Plan may not be transferred except:
by will;
by the laws of descent and distribution;
if permitted by the committee and so provided in the award agreement, pursuant to a domestic relations order; or
in the case of stock options only, if permitted by the committee and if so provided in the award agreement, to immediate family members or to a partnership, limited liability company or trust for which the sole owners, members or beneficiaries are the participant or immediate family members.
Payment of Withholding Taxes. We may withhold from any payments or stock issuances under the Plan, or collect as a condition of payment, any taxes required by law to be withheld. The participant may, but is not required to, satisfy his or her withholding tax obligation by electing to deliver currently owned shares of common stock or to have the company withhold, from the shares the participant would otherwise receive, shares, in each case having a value at least equal to the minimum amount required to be withheld and not in excess of the applicable estimated incremental tax rate approved by the committee. This election must be made prior to the date on which the amount of tax to be withheld is determined.
Prohibition of Repricing. Under the Plan, the committee may not, without the approval of the company’s stockholders, authorize the repricing of any outstanding option or SAR to reduce its exercise price, cancel any option or SAR in exchange for cash or another award when the exercise price exceeds the fair market value of the underlying shares, or take any other action with respect to an option or SAR that the company determines would be treated as a repricing.

Federal Income Tax Consequences of Awards

The federal income tax consequences related to the issuance of the different types of awards that may be granted under the Plan are summarized below. Participants who are granted awards under the Plan should consult their own tax advisors to determine the tax consequences based on their particular circumstances.
Stock Options. A participant who is granted a stock option normally will not realize any income, nor will our company normally receive any deduction for federal income tax purposes, in the year the option is granted. When a non-qualified stock option granted through the Plan is exercised, the participant will realize ordinary income measured by the difference between the aggregate purchase price of the shares acquired and the aggregate fair market value of the shares acquired on the exercise date. An employee generally will not recognize any income upon the exercise of any ISO, but the excess of the fair market value of the shares at the time of exercise over the option price will be an item of tax preference, which may, depending on particular factors relating to the employee, subject the employee to the alternative minimum tax imposed by Section 55 of the Internal Revenue Code. The alternative minimum tax is imposed in addition to the federal individual income tax, and it is intended to ensure that individual taxpayers do not completely avoid federal income tax by using preference items. An employee will recognize capital gain or loss in the amount of the difference between the exercise price and the sale price on the sale or exchange of stock acquired pursuant to the exercise of an ISO, provided the employee does not dispose of such stock within two years from the date of grant and one year from the date of exercise of the ISO (the holding periods). An employee disposing of such shares before the expiration of the holding periods will recognize ordinary income generally equal to the difference between the option price and the fair market value of the stock on the date of exercise. The remaining gain, if any, will be capital gain.
If the exercise price of a non-qualified option is paid by the surrender of previously owned shares, the basis and the holding period of the previously owned shares carry over to the same number of shares received in exchange for the previously owned shares. The compensation income recognized on exercise of these options is added to the basis of the shares received. If the exercised option is an ISO and the shares surrendered were acquired through the exercise of an ISO and have not been held for the holding periods, the optionee will recognize income on such exchange, and the basis of the shares received will be equal to the fair market value of the shares surrendered. If the applicable holding period has been met on the date of exercise, there will be no income recognition and the basis and the holding period of the previously owned

43



shares will carry over to the same number of shares received in exchange, and the remaining shares will begin a new holding period and have a zero basis.
Stock Appreciation Rights. Generally, a participant who is granted a SAR under the Plan will not recognize any taxable income at the time of the grant. The participant will recognize ordinary income upon exercise equal to the amount of cash or the fair market value of the stock received on the day it is received.
Restricted Stock. Unless the participant makes an election to accelerate recognition of the income to the date of grant (as described below), the participant will generally not recognize income at the time the restricted stock award is granted. When the restrictions lapse, the participant will recognize ordinary income equal to the fair market value of the shares as of that date. If the participant files an election under Section 83(b) of the Internal Revenue Code within 30 days of the date of grant of restricted stock, the participant will recognize ordinary income as of the date of the grant equal to the fair market value of the stock as of that date. Any future appreciation in the stock will be taxable to the participant at capital gains rates. If the stock is later forfeited, however, the participant will not be able to recover the tax previously paid pursuant to a Section 83(b) election.
Restricted Stock Units. A participant will not be deemed to have received taxable income upon the grant of RSUs. The participant will be deemed to have received taxable ordinary income at such time as shares are distributed with respect to the RSUs in an amount equal to the fair market value of the shares distributed to the participant. The basis of the shares received will equal the amount of taxable ordinary income recognized by the participant upon receipt of such shares.
Other Stock-Based Awards. Generally, a participant who is granted any other stock-based award under the Plan will recognize ordinary income at the time the cash or shares of common stock associated with the award are received. If stock is received, the ordinary income will be equal to the excess of the fair market value of the stock received over any amount paid by the participant in exchange for the stock.
Tax Impact on the Company. We will generally be entitled a to a deduction equal to the amount of ordinary income that the participant is required to recognize as a result of the exercise or vesting of an Award, provided that the deduction is not otherwise disallowed under Section 162(m) of the Internal Revenue Code.
Section 409A. If any incentive constitutes non-qualified deferred compensation under Section 409A of the Internal Revenue Code, it will be necessary that the award be structured to comply with Section 409A of the Internal Revenue Code to avoid the imposition of additional tax, penalties and interest on the participant.
Tax Consequences of a Change of Control. If, upon a change of control of the company, the exercisability, vesting or payout of an award is accelerated, any excess on the date of the change of control of the fair market value of the shares or cash issued under accelerated awards over the purchase price of such shares, if any, may be characterized as “parachute payments” (within the meaning of Section 280G of the Internal Revenue Code) if the sum of such amounts and any other such contingent payments received by the employee exceeds an amount equal to three times the “base amount” for such employee. The base amount generally is the average of the annual compensation of the employee for the five years preceding such change in ownership or control. An “excess parachute payment” with respect to any employee is the excess of the parachute payments to such person, in the aggregate, over and above such person’s base amount. If the amounts received by an employee upon a change of control are characterized as parachute payments, the employee will be subject to a 20% excise tax on the excess parachute payment and we will be denied any deduction with respect to such excess parachute payment.
The foregoing discussion summarizes the federal income tax consequences of awards that may be granted under the Plan based on current provisions of the Internal Revenue Code, which are subject to change. This summary does not cover any foreign, state or local tax consequences.

Plan Benefits

Awards under the Plan are subject to the discretion of the committee and no determinations have been made by the committee as to any awards that may be granted pursuant to the Plan. Therefore, it is not possible to determine the benefits that will be received in the future by participants in the Plan or the benefits that would

44



have been received by such participants if the Plan had been in effect in the fiscal year ended December 31, 2017. No awards have been issued under the Plan as it is not yet effective.

Certain tables above, under “Executive Compensation – Executive Compensation Tables,” including the 2017 Summary Compensation Table, Grants of Plan-Based Awards table, Outstanding Equity Awards at December 31, 2017, and Stock Vested table and the Director Compensation table under “Director Compensation” set forth information with respect to prior awards granted to our NEOs and directors under our current stock incentive plan.

(2) As of December 31, 2017, there were 400,289 shares remaining available for future
issuance under the Stock Incentive Plan, all of which could be issued pursuant to awards of stock options, restricted stock, or “other stock-based compensation.”
In early 2018, the compensation committee granted equity awards to employees, including 249,759 RSUs and 77,690 performance share units (representing the target award). Following these grants and the return of 22,153 shares to the pool as a result of withholdings and forfeitures, there are currently less than 20,000 shares remaining available for future grant under our current plan.

Vote Required to Adopt the 2018 Stock Incentive Plan

Approval of this proposal requires the affirmative vote of a majority of the common stock present in person or by proxy and entitled to vote on the proposal. For more information on the voting requirements, see “Questions and Answers about the Proxy Materials, Annual Meeting and Voting.”

For a discussion of the treatment of a properly signed and dated proxy card without voting instructions on any or all of the proposals, please see the question below titled “What happens if I do not submit voting instructions for a proposal? What is discretionary voting? What is a broker non-vote?
Beneficial Owners
If your shares of our common stock are held in a stock brokerage account by a bank, broker, trustee or other nominee, you are considered the beneficial owner of shares held in street name and these proxy materials are being forwarded to you by your bank, broker, trustee or other nominee that is considered the stockholder of record of those shares. As the beneficial owner, you have the right to direct your bank, broker, trustee or other nominee on how to vote your shares of our common stock via the internet or telephone, if the bank, broker, trustee or other nominee offers these options or by completing, signing, dating and returning a voting instruction form provided. Your bank, broker, trustee or other nominee will send you instructions on how to submit your voting instructions for your shares of our common stock.
What happens if I do not submit voting instructions for a proposal? What is discretionary voting? What is a broker non-vote?
If you are a stockholder of record and you properly complete, sign, date and return a proxy card or voting instruction form, your shares of our common stock will be voted as you specify. If you are a stockholder of record and you sign, date and return a proxy card but make no specifications on yourproxy card, your shares of our common stock will be voted in accordance with the recommendations of our board of directors, as provided above.
If you are a beneficial owner and you do not provide voting instructions to your bank, broker, trustee or other nominee holding shares of our common stock for you, your shares of our common stock will not be voted with respect to any proposal for which the stockholder of record does not have discretionary authority to vote. Rules of the New York Stock Exchange (NYSE) determine whether proposals presented at stockholder meetings are “discretionary” or “non-discretionary.” If a proposal is determined to be discretionary, your bank, broker, trustee or other nominee is permitted under the NYSE rules to vote on the proposal without receiving voting instructions from you. If a proposal is determined to be non-discretionary, the NYSE rules prohibit your bank, broker, trustee or other nominee to vote on the proposal without receiving voting instructions from you. A “broker non-vote” occurs when a bank, broker, trustee or other nominee holding shares for a beneficial owner returns a valid proxy, but does not vote on a particular proposal because it does not have discretionary authority to vote on the matter and has not received voting instructions from the stockholder for whom it is holding shares.
Under the NYSE rules, the proposal relating to the ratification of the appointment of our independent registered public accounting firm is the only discretionary proposal being presented at the meeting. Thus, if you are a beneficial owner and you do not provide voting instructions to your bank, broker, trustee or other nominee holding shares for you, your shares may be voted by the record holder with respect to the ratification of the appointment of Grant Thornton LLP is expected to be available at the 2017 Annual Meeting and will have the opportunity to make a statement, if he or she wishes, and to respond to appropriate questions from stockholders.

The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 5.4 hereof) affecting the Company, or the financial statements of the Company or any Subsidiary, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

11.3Cancellation. Any provision of this Plan or any Award Agreement to the contrary notwithstanding, if permitted by Section 409A, the Committee may cause any Award granted hereunder to be canceled in consideration of a cash payment or alternative Award made to the holder of such canceled Award equal in value to such canceled Award. Notwithstanding the foregoing, except for adjustments permitted under Sections 5.4 and 11.2, no action by the Committee shall, unless approved by the stockholders of the Company, (a) cause a reduction in the exercise price of Options or SARs granted under the Plan or (b) permit an outstanding Option or SAR with an exercise price greater than the current fair market value of a Share to be surrendered as consideration for a new Option or SAR with a lower exercise price, shares of Restricted Stock, Restricted Stock Units, and Other Stock-Based Award, or Common Stock.

11.4Change of Control.

(ii)    require that all outstanding Options and SARs be exercised on or before a specified date (before or after such Change of Control) fixed by the Committee, after which specified date all unexercised Options and SARs shall terminate;

A-8



(iii)    arrange or otherwise provide for the payment of cash or other consideration to Participants representing the value of such Awards in exchange for the satisfaction and cancellation of outstanding Awards; provided, however, that the case of any Option or SAR with an exercise price that equals or exceeds the price paid for a Share in connection with the Change of Control, the Committee may cancel the Option or SAR without the payment of consideration therefor; or

(iv)    make such other modifications, adjustments or amendments to outstanding Awards or this Plan as the Committee deems necessary or appropriate, subject however to the terms of Section 5.4.

11.5Withholding.

(a)    A Participant shall be required to pay to the Company, and the Company shall have the right to deduct from all amounts paid to a Participant (whether under the Plan or otherwise), any taxes required by law to be paid or withheld in respect of Awards hereunder to such Participant.
(b)    At any time that a Participant is required to pay to the Company an amount required to be withheld under the applicable tax laws in connection with the issuance of Shares under the Plan, the Participant may, if permitted by the Committee, satisfy this obligation in whole or in part by delivering currently owned Shares or by electing (the “Election”) to have the Company withhold from the issuance Shares, which Shares shall have a value at least equal to the minimum amount required to be withheld for federal and state tax purposes, including payroll taxes, and not in excess of the applicable estimated incremental tax rate, provided such rate will not cause adverse accounting consequences and is permitted under applicable IRS withholding rules. The value of the Shares delivered or withheld shall be based on the fair market value of the Shares on the date as of which the amount of tax to be withheld shall be determined in accordance with applicable tax laws (the “Tax Date”).

(c)    Each Election to have Shares withheld must be made prior to the Tax Date. If a Participant wishes to deliver Shares in payment of taxes, the Participant must so notify the Company prior to the Tax Date. If a Participant makes an election under Section 83(b) of the Code with respect to shares of Restricted Stock, an Election to have Shares withheld is not permitted; provided, however, that no election under Section 83(b) of the Code may be made unless permitted by the terms of the applicable Award Agreement or by written consent of the Committee.

11.6Transferability.
(a)    No Awards granted hereunder may be sold, transferred, pledged, assigned, or otherwise encumbered by a Participant except:

(b)    To the extent that an Incentive Stock Option is permitted to be transferred during the lifetime of the Participant, it shall be treated thereafter as a Nonqualified Stock Option. Any attempted assignment, transfer, pledge, hypothecation, or other disposition of Awards, or levy of attachment or similar process upon Awards not specifically permitted herein, shall be null and void and without effect. The designation of a Designated Beneficiary shall not be a violation of this Section 11.6(b).

11.9No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of or as a consultant or adviser to the Company or any Subsidiary or in the employ of or as a consultant or adviser to any other entity providing services to the Company. The Company or any Subsidiary or any such other entity may at any time dismiss a Participant from employment, or terminate any arrangement pursuant to which the Participant provides services to the Company or a Subsidiary, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement. No Eligible Individual or other person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Eligible Individuals, Participants or holders or beneficiaries of Awards.

11.10Effect of Termination of Continuous Service. In the event of a Participant's termination of Continuous Service for any reason, any Awards may be exercised, shall vest or shall expire at such times as may be determined by the Committee and provided for in the Award Agreement or an amendment thereto.

11.11Governing Law. The validity, construction, and effect of the Plan, any rules and regulations relating to the Plan and any Award Agreement shall be determined in accordance with the laws of the State of Delaware.

11.13No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company.

11.14No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated, or otherwise eliminated.

11.15Compliance with Law.
(a)    U.S. Securities Laws.

(b)    Other Jurisdictions.

The Company may adopt sub-plans and establish escrow accounts and trusts as may be receivedappropriate or applicable to particular locations and countries.

11.16Section 409A of the Code. The Plan is intended to comply with Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and administered to be in compliance therewith. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless any Applicable Law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required to avoid accelerated taxation and tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to the Plan during the six (6) month period immediately following a Participant's termination of Continuous Service shall instead be paid on the first payroll date after the six-month anniversary of the Participant's separation from service (or the Participant's death, if earlier). Notwithstanding the foregoing, neither the Company nor the Committee shall have any obligation to take any action to prevent the assessment of any excise tax or penalty on any Participant under Section 409A and neither the Company nor the Committee will have any liability to any Participant for such tax or penalty.

A-11




11.17    Deferral Permitted. Payment of cash or distribution of any Shares to which a Participant is entitled under any Award shall be made as provided in the Award Agreement. Payment may be deferred at the option of the Participant if provided in the Award Agreement.

11.18Clawback Provisions. All Awards (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to any Company clawback policy implemented to comply with Applicable Laws, including any clawback policy adopted to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, as set forth in such a clawback policy or the Award Agreement.

11.19Headings. Headings are given to the subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

12.Term of the Plan. Subject to Section 11.1, no Awards may be granted under the Plan after May 2, 2028, which is ten years after the date the Plan was last approved by the Company's stockholders; provided, however, that Awards granted prior to such date shall remain in effect until such Awards have either been satisfied, expired or canceled under the terms of the Plan, and any restrictions imposed on Shares in connection with their issuance under the Plan have lapsed.
